Here are some simple instructions: ===================Set up Docker on A...

Re: Elegant on a GPU?

Spencer, I wonder if you have tried the existing Pelegant for your simulations on multi-core computers or parallel computers. By saying "implement pelegant", do you mean "install Pelegant", or "implement a version of elegant with GPU"? There is an on-going project for the GPU- based elegant in devel...

Re: Where is "plotTwiss"

You can either add full path before the command
/usr/local/oag/apps/src/tcltkapp/oagapp/plotTwiss
or add the path to the PATH environment variable.

Re: in mode r: No such file or directory

You can also try

elegant -rpnDefns=<filename>

in the command line.

Re: SCRIPT causing hangs

Joel,

The SCRIPT element is supported in the new Pelegant 25. It is going to be processed by the Master CPU.

Re: element#1.Particles in optimization with Pelegant

Wanming,

A bug has been found for the simplex method in Pelegant when the optimization term has "transmission". It will be fixed in the next release.

Re: element#1.Particles in optimization with Pelegant

Wanming,

Can you provide a simplified test case, so we can reproduce the problem?

Thanks,

Re: randomwalk with parallel optimization

In the parallel optimization methods, both swarm and genetic are supposed to be global optimization methods. The hybridsimplex should give a result at least better than the default (serial simplex) method with the same configuration, where an independent simplex method will be conducted on each of t...

Re: problem compiling Pelegant // missing libpgapack.a

Philippe,

The PGAPACK should come with the latest SDDS library. You do not need install it separately yourself.

Re: Memory Allocation Error

The minimum theoretical memory requirement for this simulation is 8(double) x 7(6-dimensions+1ID) x 1e8=5.6GB, while it requires much more in practice. So a 32-bit system with memory limit of 4GB will not meet the memory requirement. The program tries to allocate in a contiguous space. It could fail...
